title: Synthesis of immunoglobulins by human endocervix in organ culture.
abstract: The synthesis of immunoglobulins by the uterine cervix was investigated in an endocervical organ-culture system. Using Ouchterlony immunodiffusion gels immunoglobulin G, immunoglobulin A and secretory piece were detected in washings of endocervical explants and in explant incubation medium. Synthesis of immunoglobulin in the organ-culture system was investigated by polyacrylamide-gel electrophoresis of radiolabelled polypeptides; 2 polypeptides co-migrated with the heavy and light chains of a reference polyclonal immunoglobulin G and were confirmed, by use of anti-human globulin and iodinated staphylococcal protein A, to be the heavy and light chains of immunoglobulin G. This experimental system will provide a useful model in future investigations of the efficacy of a local vaccine in human subjects.
